Shell Optimax and my P1
#1
On the M6 the other day and HAD to put some Shell Optimax in my P1. Almost instantly there seemed to be a noticable drop in top end engine performance after 5,000rpm and has remained so until filling up with Esso Super Unleaded yesterday. I know optimax is supposed to explode in the cylinder sooner during the cycle but why the drop off in top end grunt?

Think I'm the same as you P1DOG. Normally use super unleaded, put in a few tanks of Optimax and I can't see what all the fuss is about.
I'll stick with it though cause it's about £8 a tank cheaper

Although I have posted this before, its worth repeating. Ralliart UK ran back to back tests using 2 cars and Optimax gave 4 and 5 bhp extra on the 2 cars. I run it and always notice if I have to put some normal SUL in the tank.

There will ALWAYS be scare stories, generally issued from competing companies - worries a few simple minds!!
Optimax is used in all my cars - the least performance orientated ones are the ones that seem to benefit most, Oddly??
I have noticed that Optimax is creeping up faster in price however, they will push until there is a drop-off - so, it may be good for those who believe everything they read to stop buying for a while - will pull the price down!!
